Within the range of the number, the control command signal is not output to the wind force adjusting motor 41. However, in the excessive grain supply state in which both the upper grain sensor 36 and the lower grain sensor 37 detect the presence of the grain, the detected rotation speed of the compressed air rotation sensor 42 is compared with the control reference rotation speed to obtain the control reference. If the rotation speed is out of the range, a wind force increase adjustment command signal is output to the wind force adjustment motor 41 to adjust the pressure wind Karato 16 to the increase side, and the upper grain sensor 36 and the lower grain sensor 37 are also provided. In the grain under-supplied state in which both of them detect the absence of grain, the detected rotation speed of the compressed air rotation sensor 42 is compared with the control reference rotation speed, and if it is outside the control reference rotation speed, the wind force adjustment mode is set.
